Petagine, who spent six seasons in Japan, was signed by the Red Sox as a Minor League free agent on Feb. 8. His chance to make the team in Spring Training ended when he had knee surgery.
But Petagine has been ripping it up at Pawtucket, hitting .327 with 20 homers and 69 RBIs in 74 games.
"He's been tearing up Triple-A," said Red Sox manager Terry Francona. "This is a guy with a lot of experience. He's gone down there and really done what everybody has asked him to do. [Pawtucket manager] Ron Johnson has been raving about this guy for a while. A long while."
Foulke plan: The Red Sox have put a plan in motion for rehabbing closer Keith Foulke. On Monday, the right-hander will throw off a mound for the first time since his left knee surgery, which took place on July 7. Foulke will follow with mound sessions on Wednesday and Friday and then the Red Sox will evaluate the next step.
Foulke told a reporter recently that he had no interest in going on a Minor League rehab stint. However, Francona said that issue needs to be examined deeper.
"We probably have to visit that," Francona said. "We have to get him ready to pitch here. It's not like we shove him in for the third inning. We're probably going to let him need to pitch a couple of times. I think Foulkie is OK to do whatever we ask him to do. We'll evaluate where we think he is. If he needs it, we'll do it. If he doesn't need it, we'll just do what's in everybody's best interest."
One reason the Red Sox need to be as concise as they can with Foulke's schedule is that his return might coincide with Curt Schilling's return to the rotation.
Ortiz walks on: One side effect of Manny Ramirez's recent on-again, off-again status has been the careful way in which pitchers have worked David Ortiz.
The big designated hitter, who is the first to admit that plate discipline isn't his strength, has drawn nine walks in his last six games.
Ramirez went down with contusions on the right side of his face and his chest in Wednesday's game, meaning Ortiz could be without his fellow slugger for the next day or two.
On deck: Clement will face right-hander D.J. Carrasco in the Thursday matinee of this three-game series.
